Wilkinson Ingrid C E , Martin Lee , Grossman Ashley B , Monson John P , Akker Scott , Savage Martin O , Drake William M , Storr Helen L

Background: The Low dose dexamethasone suppression test (LDDST) is an important investigation for suspected Cushing’s Syndrome (CS). The traditional definition of normal suppression of serum cortisol to ≤50 nmol/l during the LDDST (0.5 mg 6 hrly × 48 h) comes from a time when biochemical autoanalysers did not routinely detect very low values. Previous studies reported 5.1–8.3% of patients with Cushing’s Disease (CD) suppressed to <50 nmol/l at 48 ...

Introduction: Diabetic ketoacidosis (DKA) as an inflammatory state combined with the disruption of the normal coagulation cascade can lead patients to an increased risk of thrombosis. Especially, patients that are genetically susceptible to thrombosis could develop deep venous thrombosis (DVT) due to inflammation, dehydration, and hyperviscosity secondarily to DKA. It is noteworthy that children with DKA who underwent central venous catheter placement could develop DVT, especi...

Introduction: Neuropathy, as a complication of type 1 diabetes (T1D), is a heterogeneous group with chronic polyneuropathy being the most frequent form. Acute mononeuropathy is rare and its pathophysiology has not been elucidated.Purpose: To describe acute mononeuropathy during the course of severe ketoacidosis in an 8-year-old girl diagnosed with T1D.Case report: An 8-year old girl was admitted to the Emergency Department because ...

Introduction: HLA-G gene is involved in the control of immune response. It plays a primary role on immune tolerance and may participate in controlling autoimmune responses serving as a potential independent susceptibility marker. HLA-G has been isolated in some secretory granules and on the cell surface of primary islet cells induced to secrete insulin. Subsequently, it could be hypothesized that HLA-G methylation at pancreatic islet could sustain T cell activation and onset o...

Introduction: Autoimmune Polyglandular Syndrome Type 1 (APS-1) is a rare autosomal recessive hereditary disorder resulting from a mutation in the AIRE gene. APS-1 is characterized by three classic clinical features: hypoparathyroidism, Addison’s disease and chronic mucocutaneous candidiasis. Additionally to the classic triad, the phenotype of APS-1 includes several endocrine and non-endocrine autoimmune manifestations. Purpose:Topresent a rapid onset and progression of ch...

Background: Transient Generalized Glucocorticoid Hypersensitivity (TGGH) is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the underlying molecular mechanisms have not been fully elucidated.Objective and hypotheses: To present the clinical manifestations, endocrinologic evaluation and molecular studies in ...

Background: Hyponatremia is defined as a serum sodium level below 135 mEq/l. It is associated with increased morbidity and mortality. Hyponatremia has many causes and can be classified as acute/chronic or hypo/hypo/euvolemic. The main rule in fluid and electrolyte disorders (and especially in hyponatremia) is excluding hypothyroidism and hypocortisolism and then making the correct diagnosis. Hypothyroidism and hypocorticolism can also cause euvolemic chronic hyponatremia but t...

Search for Genetic Defects in the Transcription Factor Genes FOXL2, FOXE1, BMP15, NOBOX, and GDF9 in Children, Adolescents and Young Adults With Premature Ovarian Insufficiency POI

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...

Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...
